Pick a filter! `ffmpeg -pix_fmts` Watch out - there are a lot!Ĥ. Probe it! `ffmpeg -i new_file.mkv` This one should be set to `yuv420p(progressive)`ģ. i /dev/urandom -ar 48000 -ac 2 -f s16le -i /dev/urandom -codec:a copy \ġ. center(/img/smpte-fuzzed2.png)]įfmpeg -f lavfi -i nullsrc=s=1280x720 -filter_complex \ `ffmpeg -i new_file.mov -bsf noise=80 -map 0 -c copy fuzzed.mov` If you want MORE, you can simply up the noise filter (default is 1), like this: Play around with containers and codecs to learn how different errors manifest themselves. `ffmpeg -i new_file.mov -bsf noise -map 0 -c copy fuzzed.mov` is the basic script for adding some noise. `ffmpeg -i input.mp4 -codec:v huffyuv -bsf:v noise -codec:a copy noise.mkv` This is good for making "bad" test video files to push your player or quality analysis to its limits, especially if you repeat the noise generation in multiple sweeps. Random damage can be assigned to video and audio streams using the (). But here are some ways to manipulate or create interesting video files.įuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. ⬇️, ➡️, or spacebar 🛰 to start slidedeck.
